Lane Keeping Aid - function

Certain settings can be made for the Lane Keeping Aid (Lane Keeping Aid) function.

Off & On

Lane Keeping Aid is active within the speed range 65-200 km/h (40-125 mph) on roads with clearly visible side lines. The function is temporarily deactivated on narrow roads with less than 2.6 metres between the lane side lines.

Press the centre console's button to activate or deactivate the function. The button's lamp illuminates when the function is switched on.

Some combinations of the selected equipment leave no vacant space for an On/Off button in the centre console - in which case, the function is instead operated in the car's menu system MY CAR MY CAR. Here, proceed as follows:

  • Search for Lane Keeping Aid and then select On or Off.

In addition, the following selections can be made in MY CAR:

  • Warning with vibration in the steering wheel: Vibration only - On or Off.
  • Active steering: Steering assist only- On or Off.
  • Both Warning with vibration in the steering wheel and Active steering: Full function - On or Off.

Active steering

Lane Keeping Aid strives to keep the car within the side lines for the lane.

LKA intervenes and steers away.

If the car approaches the left or right side line of the lane and the direction indicator is not activated, the car is steered back into the lane.

Warning with vibration in the steering wheel

P4-1220-LKA Princip Varning+Styrhjälp
LKA steers and alerts with steering wheel vibration1.

If the car crosses a side line then Lane Keeping Aid will alert the driver with vibration in the steering wheel2. This occurs regardless of whether the car is actively steered back by applying a slight steering torque.

Dynamic cornering

LKA does not engage in sharp inside curves.

In certain cases Lane assistance will allow the car to cross lane lines without engaging active steering or activating a warning. Using an adjacent lane for cutting a corner when there is a clear line of vision is an example of this.

  2. 2 Steering wheel vibration varies - the longer the time for which the car has crossed the side line, the more pulses there are.
